1. Ch.1. Introduction  Environmental Geochemistry? The application of chemical principles to predicte the fate of organic and inorganic pollutants at the earth's surface and in the atmosphere (R.Stoessel) Applying geochemical knowledge to solve environmental problems

2. Ch.1.  Some Concepts for EG Earth is a closed but dynamic system  It stays in the system but cycles through the system (e.g. rock cycle, water cycle, sulfur cycle, etc.) Earth is practically the only home for human beings within our reach in the Universe Need to balance development with conservation  Sustainability!! Environmental impact may seem little before getting the critical point A lot slower recovery than pollution, which is of course extremely expensive  Problems for generation after generation Recovery (restoration, remediation) is never perfect. Environmental Science is a comprehensive study field
